Title: "anti-static, anti-smearing pre-stretched and pressed flat, precision-cut striped flexible covering for transfer cylinders.
Inventor: DEMOORE HOWARD WARREN
IPC: B41F13/193
Filed: 1997-01-07
Abstract: Freshly printed sheets are transferred from one printing unit to another by transfer cylindrs each having an ink repelent, electrically conductive, striped flexible jacket covering that is movable relative to the sheet support surface of the transfer cylinder. The jacket covering is made of a flexible fabric material that is pre-stretched, pressed flat, cut to size and treated with an ink repellent compound and is also treated with an anti-static ionic compound or is otherwise rendered electrically conductive by one or more conductive strands. Electrostatic charges carried by the freshly printed sheets are discharged through the ink repellent, electrically conductive, flexible jacket covering into the grounded transfer cylinder. A low friction, electrically conductive cylindr base covering that includes center alignment marks is secured to the transfer cylinder for engaging the flexible jacket covering. The ink repellent, electrically conductive flexible jacket covering is provided with alignment center marks and alignment stripes so that the flexible jacket covering can be precisely aligned with ease and secured over the gripper edge, tail edge and side egdes of the transfer cylinder. The low frictional coefficient of the transfer cylinder base covering is further reduced by nodes and/or openings.

Title: Motor vehicle instrument panel with flexible tethering hinged air bag deployment door.
Inventor: GALLAGHER MICHAEL J
IPC: B60R21/215
Filed: 1996-03-08
Abstract: A molded motor vehicle instrument panel (10) made of a thermoplastic material has an integral air bag deployment door (14) for a passenger side air bag (22) that is defined by a tear seam (16) and is normally retained by an integral flexible mounting/hinge flange (36) to a part of the vehicle structure (11) when the seam is torn by the inflating air bag and wherein this flange then bends to allow the door to swing open to allow deployment of the air bag retaining same to the vehicle structure as the door is then free of the instrument panel. At very low temperatures, a portion of the air bag door can break away from the mounting/hinge flange because of plastic embrittlement at these low temperatures and the high bending stresses encountered at this juncture. This separation of the broken door portion from the vehicle structure is prevented by a tethering hinge (50) that is formed of a strong flexible sheet material that spans this critical juncture between the mounting/hinge flange and door and remains flexible at these very cold temperatures to retain the broken door portion to the vehicle structure.

Abstract: PCT No. PCT/CH85/00001 Sec. 371 Date Sep. 9, 1985 Sec. 102(e) Date Sep. 9, 1985 PCT Filed Jan. 10, 1985 PCT Pub. No. WO85/03030 PCT Pub. Date Jul. 18, 1985.The invention is primarily concerned with a sandwich material (55) made of sheets based on paper. This material is substantially comprised of a sheet (42) of corrugated paper (44) forming one or several layers. An intermediate paper sheet (31) is bonded to the corrugations of the sheet 42. A film (29) of a thermoplastic compound adheres physically as the result of an extrusion to the outer side of the intermediate paper sheet (31). The process for manufacturing this material consists firstly in extruding a film (29) of thermoplastic compound on the intermediate paper sheet (31), and then in bonding the web (27) of protective layer thus obtained on the corrugations of the sheet of corrugated paper (42). The invention is remarkable in that these operations are carried out on a standard machine for manufacturing corrugated paperboard. However, on the one hand an adhesive setting instantly at room temperature is used, and on the other hand the various heating elements used to bring about the setting of adhesives polymerizing through an endothermic reaction are kept switched off. The invention is particularly useful for making furniture or wall panels.
